Widespread chill in the U.P. Tuesday as the jet stream digs south of the region. The Upper Michigan wind field shifts from a more westerly direction into Tuesday morning, keeping the lake effect snow machine active over the Keweenaw and eastern county locations near the Lake Superior shore. More sunshine in store for the southern U.P., though cold air remains as much of the region will feel below seasonal daytime highs.

An upper level disturbance brings a chance of snow showers to the Lake Superior shores Wednesday morning, but mild weather builds, briefly, late Wednesday into Thursday morning.

Towards Thursday afternoon, a Canadian Prairies system draws in a southerly moisture stream from the Central Midwest to bring widespread snow chances to the U.P.

Another system comes late Friday, based from the Central Plains to deliver a wintry mix to the region, and following in its wake, lake effect snow in the north wind belts Saturday.
